A. general description of the operation of the machine will facilitate an understanding of the invention. The machine comprises, in general, a hopper adapted to hold the mix in whichthereis a suitable agitator. Ad-

out and jacen't the mouth of the hopper is rotatable 9 mold cavity wheel. There is a measuring 7, 1927. Serial N0. 166,394.

cup and a plunger associated therewith to force a certain predetermined amount of the mix into each mold cavity as it passes the mouth of the hopper. There is also provided a reciprocal work head carrying a plur'ality of tools, namely, a first tamper, a carbon pencil inserter, a final tamper, and an ejector, adapted to operate upon each one of the mold cavities in sequence. There is also. provided means for rotating the cavity mold wheel one step at a time, and means for operating the work head for each movement of. the cavity wheel.

I will now describe the construction and operation of the machine more in detail.

As shown in the drawings, 10 indicates a suitable supporting frame upon which the machine is formed. 11 indicates a drivepulley adapted to be driven in any suitable manner as by means of a belt, and 12 indicatcs a suitable clutch of any desired construction adapted to be operated by the hand lever 13 in order to start or stop the machine in the usual manner. 1V hen the clutch is in, the wheel 11 drives the drive-shaft 1 1.

Any suitable mechanical movement is provided for causing the continuously rotating shaft 14 to rotate the wheel 15 intermittently. As here shown, the shaft lat carries a pinion 16 with a single tooth 16 adapted to engage in one of the recesses 17 in the periphery of the wheel 15 upon each rotation of the shaft 14. It. will be seen. that each rotation of theshaft 14 moves thiwhe l 15 a distance equal to the distance between the centers of two adjacent recesses 17. and that such wheel remains stationary from the time the tooth 16 leaves one of such recesses until it engages the next.

The Wheel 15 is mounted on the shaft 18 which in. turn carries the mold cavity wheel 19. 20 and 21 indicate hearings for the ends of the shaft 18. The mold cayity wheel 19 is provided with a plurality (here shown as 12) of cylindrical openings 22 passing therethrough each surrounded by a bushing 22 of suitable non-corrosive material. The

I recesses 17 in the periphery of the wheel 15 correspond in number to the mold cavities 22 so that with each movement of the wheel 15, the mold cavity wheel '19 motes a distance equal to the distance between the centers of two adjacaifitcavitics 22.,

- 23 indic fin a hopperv containing the mix 24, which isusually in powder form. This hopper is arranged just in front of the covity Wheel 19 and is provided with a mouth 25 adjacent the wheel 19. and so aligned that the mold cavities 22 will register with such mouth upon each movement of the wheel 19. Within the hopper 23 there is also provided an agitator comprising the reciprocating bar 26 carrying on its end the fork 27 with a series of prongs 28. alternat ng prongs being I curved downwardly at their ends as indicatcdby 28 The har 26 reciprocates in the hearing 29 and is operated by a crank Sf) carried on the shaft 31. which in turn is driven by a pinion 32 operated by another pinion 33 on the stub shaft 34. The stub shaft 34 is adapted to be driven in any suitahle manner by means of the belt 35, which in turn is driven by a suitable beltwheel on' the shaft 36 driven by the gear 37 meshing with the gear 38 on the shaft 14 through the intermediate gear 39, which IS loosely mounted on the shaft 18.

' The pinion 39 carries the tool operating cam 40 provided with the cam track or groove 41. 42 indicates a reeiprocable work head slidably mounted on the shaft 18 and prevented from turning by the shoe 43 sl1dably mounted in a suitable gulde 43. The work head is provided with a cam roller 44 l ng Within the cam track 41 of the cam wheel 40. and the cam track is so shaped (see Fig. 3) that upon each rotation of the cam Wheel 40 the head 42 will he moved toward the WllGPllQ and then back again. The cam l is also provided with a flattened portion and the parts are so timed that the forward and backward movement of, the cam will. take place when the Wheel 19 is stationary. and the Work head will remain withdrawn from the Wheel and stationary when the wheel 19 moves.

I will now describe the measuring cup and mg hack ot the wheel plunger or tamper used in co-n nection with the hopper for placing the init al charge oi mix in the cavity Wheel (see Fig. 4). 'llns apparatus comprises a reciproeable cnp or sleeve 45 with the plunger or tamp 46 lying inside thereof. Both the cup and the plunger are adapted for reciprocahle movement through the hoppu' 23 toward the cavity 22 lying in alignment with the mouth ot the hopper. It will be seen by reference to B 1g.

4 that the hopper is somewhat Wider than the depth of the cavity 22, so that the amount of mix measured out by insertion of the sleeve 45 is considerably larger in volume than the cavity 22. This larger mass. however, is forced or tampered by the plunger 46 into the cavity 22-. thus increasing ts (lensity to a certain extent. The measuring on p or sleeve 45 is provided wi'tlra shoe 4? op erating in the guide 48 {see Fig. 6) and is adapted to he moved by a pin 49 projecting through the slot in the guide 48. The

1 pin &9 is embraced by an eye 51 on the upper end of the arm 52, which mounted on the shaft- 53 carried by the frame 10. A spring 54 serves to yieldingly hold the arm 52 in retracted position. The arm 52' is provided with an anti-friction roller 55 hearing against the cam 56, which is mounted on the shaft tamp lG is adapted for reciprocable movement in a similar manner, except that it is slidahly mounted Within the sleeve 45 and is provided with a pin 58 engaged by an eve in the upper end of arm 59. which is similar to arm 52. The arm 59 is provided with an antifriction roller similar to the roller 55 on the arm 52. which is engaged by the cam 60 (see Fig. 4). also'mounted on the shaft 57.

The shaft 57 is continuously driven by the spiral gear 61, which in turn is operated by the spiral gear 62 on the shaftl.

The rotation of the shaft 57 is so timed and the cams When one of'the cavities 22 is adjacent the mouth of the hopper, the sleeve or measuring cup 4-5 will move through the hopper to the position indicated by the broken lines in Fig. 4. thus measuring out a charge of the mix. When the sleeve is in this position, the plunger or tam 46 will be moved to the left (as viewed in ig. 4,) to force the mix in the measuring cup into the cavity 22 and compress the same therein. Both the sleeve and plunger are then withdrawn by means of the spring 54- and a similar spring. (not is pivotally shown) on the arm 59. After the cavity 22 has received its charge, the Wheel 19 is rothe mouth. in this manner. each cavity 22 is filled with a charge of the mix as'the wheel rotates.

Arranged back of the wheel 1% is a stationary disk or backing member 63. provided with a hardened non-eorrosive plate 63 iv- 19 and forming a bottom for the mold cavities 22. i

The work head 42 carries t'onr tools. namely. a first tamper, a carbon pencil inserter. a second tamper, and an ejector, adapted to operate upon tour cavities 22 simultaneously. that is. upon any one of said cavities in sequence, since the wheel 19 moves up one step for each operation of the work head. The first tamper is indicated by 64: (Fig. 8) and comprises a short rod with its end portion reduced in diameter as indicated by 65. Upon the movement of the Work head 42. this tamper 64 compresses the mix more tightly in the cavity 22 and the point (35 forms a sliaht central depression in order to form a start for the carbon pencil to he inserted'at the next step. The tamper 64 is local-ed in a suitable bore in the head 4-2 and it is threaded and provided with two adjusting nuts-66 and 67 asshown in order to give proper adiustment. a- V The carbon pencil inserting mechanism is 57. The plunger or teasers best shown in Figs. 5, 10 and ll. 68 indi- Gates, in general, any suitable hopper adapt ed to contain a plurality of carbon'pencils c9 and feed the same downwardly.

Below the hopper for the carbon penc1ls 1s a clamping device comprising the two jaws 70 and 71, pivoted at 72 and 73 respectively, and yieldingly held together by the springs 74: surrounding the arm 75 pivotally attached to the jaw 70 as shown. The head 42 carries a plunger 7 5 and a clamp releasing rod 76 The carbon pencils are ordinarily provided with heads 69 so that in forcing the pencil into the core it is necessary to open the jaws 70 and 71 of the clamp wide enough to permit the head 69 to pass thercthrough. This is accomplished by the shoul der 7 6 on the rod'l'tl. In the forward move ment of the head 42 the rod 76 opens the jaws 70, 71, and the rod 75 forces one of the carbon pencils 69 into the mix in the cavity 22. Upon withdrawal of the head 42, the clamps 7 O and 71 are held open just long enough by the rod 7 6 for another pencil to fall in between the same to be engaged by the rod 75 upon the next forward movement of the head.

The second tamper rated by 77 is similar to the first tamper 64 and need not .he described in detail. The only di'tl'erence is that the second tamper 77 instead of being provided with the reduced portion 65 is provided with a recess T7 to This is immediately ll Oil; 46 Wl'llCll forces anion accommodate the projecting end of the carbon pencil, which is in place when the sec ond tamper operates.

The ejector Fig. 9) is indicated by TS and is also provided at end with a recess or cup T8 to accommodate lb" cud oi the carbon pencil. The ejector is slidably mounted in a sleeve 79 and is pressed forwardly by means of a spring 80. in the forward movement of the head 42 the spring 80 is compressed and when the core is almost out of the cavity 22this springexpands to throw the core a slight dislance'beyond the wheel, where it falls upon a suitable conveyor 81. The backing member (53 is provided with a hole 82 opposite the cavity 32 when it is in line with the ejector and the completed core is thrown through this hole onto the conveyor 81. The member Y9 carrying the 'ector TS is provided with adjustand 83 similar to the adjusting on the first tamper (ll.

of the measuring cup into the adjacent cavity 22. The wheel 19 then moves up a step and the next cavity is like vise filled. When the cavity comes opposit the first tamper 64, this is moved forward by the recipro cable work head 42 and the charge is tamped in the cavity and a small deprexsion is formed to receive the carbon pencil. At the next step'the carbon pencil is inserted as has been described before. At the next step the final lamp is given by means of the tool '37, and at the last step the complete. core is ejected by means of the ejector 78. I

It may be added that the feature of a measuring tube charged by plunging the tube into the mix is important. The method involved results in isolating an accurately measured charge, and then forcing the charge into the mold-cavity Where it is formed into a suitably compacted core. This results in great uniformity of product and incidentally eliminates waste, Obviously the principle may be given other embodiments than that nsed in illustrating the invention.
